Specification of Letters Patent. Patented Apr. 23, ll lld.

' Application filed June 15, 1917. Serial No. 174,985.

To all whom it may concern:

Be it known that I, Josnrrr E. KEN ISTON, a citizen of the United States, residing at Albany, in the county of Alameda and State of California, have invented certain new and useful Improvements in Die-Head Holders, of which the following 15 a specification.

This invention relates to die head holders, and is adapted particularly for use in connection with power or hand pipe threading and cutting machines.

The primary object of the inventlon is to provide an improved holder adapted for use with machines of the type above referred to, and wherein the die heads of various sizes for use with the machine are supported in close proximity to the carriage of the machine, and which may be quickly and easily applied to or removed from the carriage.

A further object of the invention 1s to provide a holder for die heads which is capable of holding or accommodating a number of die heads of various s1zes, a nd wherein the holder is located in a position convenient to the machine, and at the same time is so located as to not interfere with the operations of the machine or the efforts of the machine operator. y

Still further objects reside in providing a holder of the character described which shall be of extremely simple and inexpensive construction, which is capable of being readily applied to the machine and wh ch requires no attention after once being installed, and which will facllltate the work of the operator-of the machine with which the improved holder is used.

With these objects in view together w th others which will appear as the description proceeds, the invention resides in the novel formation, combination and arrangement of parts all as will be descrlbed more fully hereinafter, illustrated in the drawlngs and particularly pointed out in the claims.

In the drawing:

Figure 1 is an end elevat1on of a holder constructed in accordance with the invention, the holder being illustrated removed from the machine, and

Fig. 2 is a sectional view taken through a part of a conventional form of threading or cutting machine, and illustrating the proximate location of a holder constructed in accordance with the invention.

Referring now to the drawing, 5 indicates the frame of a conventional form of pipe threading and cutting machine, upon which a carriage 6 is slidably mounted. It will be understood that this carriage is capable of moving longitudinally of the frame upon suitable track-ways, and the movements of this carriage may be con trolled in any approved manner. The carriage is adapted to support the die heads indicated generally at 7, and is equipped with guides 8 for this purpose. The heads are introduced to the guideways from the ends of the carriage, and require sliding movement for their application or removal from the carriage.

The invention comprehends the arrangement of a frame 9 adjacent the machine, and which frame carries a plurality of racks or holders indicated at 10, the said holders being adapted to contain-die heads for use upon, the machine. These holders or racks are equipped with guides 11 similar to those upon the carriage supporting the die heads, and between which the die heads are a dapted to fit. In the present instance, the frame 9 is provided with a pair of legs 12, the latter being bolted or in any other manner secured to the threading machine, and the frame is positioned upon the machine in such manner that the racks carried thereby are disposed at their ends adjacent and slightly removed from the carriage 6 upon the machine. It will also be observed, particularly in Fig. 2 of the drawing, that the guideways 11 upon, the racks 10 are alined with the guides 8 upon the carriage so that the die heads may be slid either from the carriage into the racks 10, or from the racks into the guides upon the carriage. There may be anydesired number of racks 10 upon the frame 9, and the racks are adapted to accommodate the die heads for cutting or operating upon work of different sizes.

When it is desired to apply a die head to the carriage, the latter is moved longitudinally of its supporting frame until the guideways 8 thereof are in register with the guideways 11 upon the rack which supports the die head of the desired dimension. The die head is then moved by being slid longitudinally of the guideways 11 until the same moves into the trackways 8 upon the carriage. When it is desired to remove the die heads from the carriage the reverse of this operation is performed.
